Encyclopedia
Phragmidium violaceum is a plant pathogen native to Europe
, Africa
, and the Middle East
. It primarily infects Rubus
species.
It has been used in the biological control of invasive blackberry species in Chile
, Australia
, and New Zealand
. In 2005, it was discovered growing on Himilayan blackberry
plants in Oregon
. This accidental introduction does not appear to be infecting native vegetation, so it offers hope for reducing the impact of invasive blackberries in the Pacific Northwest
